A self-fastening threaded insert is described, with respect to a slab of building material, comprising a bearing element with respect to the slab, a deformation element adapted to interact with the slab, and a supporting element cooperating with the bearing element. The deformation element is deformed due to the effect of an external load transmitted by the supporting element, and is adapted to transmit to the slab forces which are perpendicular to an application force of the external load to be able to fasten the threaded insert to the slab. A process for assembling such threaded insert is also described.

The present invention refers to a self-fastening threaded insert and to a process for assembling a threaded insert. In particular, the present invention refers to a self-fastening threaded insert with respect to a slab of building material.
Generally, a self-fastening threaded insert allows arranging a threaded seat on a slab of building material, such as marble, granite or other stone material, wood, glass and composite material, such as carbon and further new-generation elements of a compact nature known as “solid surfaces”.
Such threaded seat allows fastening the slab to a structure or frame to make vented facades, building coatings, building environments, furniture, sanitary elements, kitchens, funeral works of art, etc.
The prior art, represented for example, by EP1277973 B1, refers to a small fastening block comprising a cylindrical separating body with an internal drilling. The body is axially divided into two segments, mutually connected by snap-type closures. A separating device is housed in a body recess. However, in order to fasten the small block to the slab, it is necessary to rotate the body with a tool, creating an insertion effect in the slab hole.
Object of the present invention is providing a self-fastening threaded insert which allows avoiding to have to recur to external means for assembling, once having obtained a hole when working with the use of standard means.
A further object is providing a self-fastening threaded insert which allows a completely disappearing assembling, without external encumbrances, to facilitate handling and storing the slabs.
The above and other objects and advantages of the invention, which will result from the following description, are obtained with a self-fastening threaded insert as claimed in claim 1.
Moreover, the above and other objects and advantages of the invention, which will result from the following description, are obtained with a process for assembling a self-fastening threaded insert as claimed in claim 10.
Preferred embodiments and non trivial variations of the present invention are the subject matter of the dependent claims.
It is intended that all enclosed claims are an integral part of the present description.
It will be immediately obvious that numerous variations and modifications (for example related to shape, sizes, arrangements and parts with equivalent functionality) could be made to what is described, without departing from the scope of the invention as appears from the enclosed claims.
The present invention will be better described by some preferred embodiments thereof, provided as a non-limiting example, with reference to the enclosed drawings, in which:
With reference to
Advantageously, such at least one deformation element 20 is deformed due to the effect of an external load transmitted by the supporting element 30. In this way, such at least one deformation element 20 can transmit to the slab forces which are perpendicular to an application force of the external load, to allow the threaded insert 1 to get fastened to the slab.
Advantageously, the supporting element 30 can support a battery of deformation elements 20, preferably in a number ranging at least three elements connected. in series or more, depending on applications.
With reference to
With reference to
At least one of such deformation elements 20 can comprise an elastic toothed crown, adapted to be housed with interference in a cylindrical recess of the slab. As shown in
Alternatively, each deformation element 20 can comprise a smooth or toothed cup spring, adapted to be housed with interference in a cylindrical recess of the slab (not shown).
According to a preferred configuration, each deformation element 20 can be connected to at least one spacer ring 21, as shown in
With reference to
Preferably, the abutting means can comprise a blind threaded hole or a partially threaded through-hole or prevent a screw T from pressing onto the bottom of the recess of the slab.
With reference to
The bearing element 10 made of plastic or metallic material, depending on the application, and the supporting element 30 made of metal allow supporting loads with a high force.
A process for assembling a self-fastening threaded insert 1 with respect to a slab of building material comprises the steps of:
The threaded insert 1 allows obtaining the objects of the invention, with the advantages of allowing an assembling after having performed a simple hole on the slab, even when working, with the use of standard tools, being able to quickly insert the threaded insert into such hole through a simple pressure, without having to add adhesives and gluing agents.
Moreover, the threaded insert of the invention allows performing an assembling of the threaded insert with disappearing, without external encumbrances, facilitating handling and storage of the slabs.
A further advantage is given by the absence of stresses on the receiving material when the threaded insert is not stressed, while during its use the elastic washers are stressed by an axial traction force, radially acting against the walls due to flexure and pressure, preventing the insert from going out of the slab.
The threading of the supporting element made as non-through ensures the fastening of the threaded insert onto the slab, avoiding the extraction effect generated by the possible inappropriate length of the screw.
